Are there any premium Chinese steels?

One of the common traits of Chinese D2 is very low vanadium content, but since D2 has pretty wide ranges for its formula you can go pretty low and still be “real” D2, albeit with too little vanadium to do much good.

One thing I've seen before is 9Cr13 being passed off as D2 because aside from the low carbon and vanadium it's kinda similar.
 
Would that explain ^ why some people who get a China D2 knife say that they were surprised how relatively easy it was to get hair shaving sharp? My general experience with D2 is its a fantastic tough steel but don't bother with getting it much past toothy sharp. Whereas the 9CR13 that I've tried on a Spyderco Mule was able to get a very sharp edge and hold it much like 440C. The people who thought they were getting D2 were in actually getting a decent enough variant that was closer to 440C...

They tend to use the best quality ss available at the time of manufacture :)
However, they never disclose details about steel type.
Who knows, maybe it would tantamount to exposing a state secret...

Hello dear,

Could you please inform me about complete name of ZHANG ZHI knife in the photo ? I couldn' find their website :((((
 
back on topic - the one 'premium' steel they have done recently is ar-rpm9 (which is the only 'pm' steel they've made - exclusively for cjrb & artisan cutlery iirc - but maybe more use it now)

many threads here have talked about it - this is a good example

Initial Impressions-AR RPM9 Steel and Blades

I own two knives in this steel: CJRB Crag and Artisan Cutlery Arroyo. Both have seen medium use since purchase. After moderate dulling of the edges, I sent both to the whetstones (1000 and 6000 grit) and then to the leather strop using 1 micron (approximate) green compound. I was very impressed...
